A brief study on control structure of grid connected PV inverter

Abstract

For stability and good efficiency of any system the controlling of that system at different loading condition is an important factor. In grid connected PV system, power converters plays major role for conversion process. At the same time controlling of power converter is very critical. This paper presents brief study on different controller used to control grid connected PV inverter by which inverter can provide stable output with low Total harmonic distortion (THD) as per standards like IEEE 1547 etc under different grid loading condition.
